Sizing tool
SECH offers an online sizing tool that enables you to independently design an energy storage solution. The proposed designs are based on SECH’s line of ultracapacitor cells and modules. The tool offers various options to consider different application conditions.
World’s first E-STATCOM
Siemens Energy, in collaboration with TenneT Germany, has developed the world’s first E-STATCOM, providing synthetic inertia and stability for renewable-ready grids. This innovative installation delivers ±200 MW of grid-forming stability, powered by SECH ESS ultracapacitor modules.
